Thanks to Rick for this one.
A Welsh rugby fan cut off his own balls after his team won.
From Reuters:

Geoff Huish, 26, was so convinced England would win Saturday's match he told fellow drinkers at a social club, "If Wales win I'll cut my balls off," the paper said. Friends at the club in Caerphilly, south Wales, thought he was joking.

But after the game Huish went home, severed his testicles with a knife, and walked 200 yards back to the bar with the testicles to show the shocked drinkers what he had done. Huish was taken to hospital where he remained in serious condition, the paper said.

Actually, I made the same pledge during the Playoffs last year, fortunately the Angels played like crap, thus allowing my boys to hang around for another season.

heh.
